Suits MK4 & MK4.5 Focus ST Models

INSTALL DOES NOT REQUIRE BUMPER REMOVAL


Details:

Get the Flow-Lock Rear Diffuser for your Ford MK4 Focus ST or MK4.5 Focus ST, which shares the same durability and technology as our renowned WRXGolf GTI & Hyundai i30N line up which is trusted by car enthusiasts worldwide. The rear valance and diffuser fins will clear the Focus ST dual exhaust and rear bumper removal is not necessary for installation of the diffuser.

The Flow-Lock interlocking system allows for the final assembly of the diffuser fins without tools or fasteners. A simple push and click and the kit is assembled and ready for installation - this means zero exposed hardware giving you the cleanest look for your MK4 Focus ST or MK4.5 Focus ST rear bumper. 

Valance is installed to the car through bolts and nuts while the Flow-Lock diffuser fins simply click into the valance (once locked into the valance it is secure). It is also possible to install when your car is on the ground.


Kit Includes:

  • MK4 & MK4.5 Focus ST Rear Valance
  • MK4 & MK4.5 Focus ST Flow-Lock Diffuser Fins
  • 2 Flow Designs stickers
  • Fitting kit with black stainless hardware
